hi there Board members, i have learnt a lot over the last couple of years from this board and for financial and other reasons i have not migrated to Mac. I have done a search of this board before posting but no one past post has really answered the knowledge that i'm seeking. On Sweetwater's website i came across this url http://www.sweetwater.com/store/detail/Logic5ProUp/ that shows the upgrade to Logic Pro 6 ($199) in the latest edition of EM - (April - pg 35) i have also read that there are 3 ways to upgrade and that from Logic Gold/Platinum 5 (which i have cross platform permanent codes for) or 6 the upgrade is called Upgrade A. I already have most of the soft synths and i would like to know what i would have to pay for the upgrade to Logic Pro 6 from my version of 5.5.1 on Windows. I know that i don't get logic pro 6 for the PC but i think that i should upgrade at least my xskey to Pro 6 so that i can use all features of Pro 6 on a mac if i finally migrate and still be able to use all the soft synths on the 5.5.1 version on PC. I would like to use the software instruments that i don't have, on my PC - will my XSKey be authorised for the mac version, and more importantly, the PC version for the following instruments if it upgrade to Pro 6 ... ES1, EVOC20, EXS24mkII, ES1 (which is what i don't have). Ok lets assume that i buy the Pro6 upgrade A mentioned above and send the temporary code to emagic - they should be able to send me the type A (permanent) codes for all aspects of Pro 6 even if i have not installed the upgrade on a mac right. I could then enter these permanent codes on my PC and authorise everything - even space designer (which i know won't work on a PC) Or will i have to install Platinum 5 on a Mac, Plug in my xskey, then the Upgrade to Pro 6 on a Mac and then authorise it for Logic Pro 6 there and then take the xskey and be able to use it on my PC. - which means i'll have to borrow someone's mac just to authorise the xskey and then uninstall it from their system. Any help regarding this technicality will be much appreciated - Thx for any feedback and sorry for bothering you all with something that may not be that important to most of you already on Logic 6 Vim
